Description

Technical Field

[0001] The utility model relates to the technical field of accessories processing, in particular to a grinding and polishing device for mechanical accessories. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. During polishing, the high-speed rotating polishing wheel is pressed against the workpiece, causing the abrasive to roll and slightly cut the workpiece surface, thereby obtaining a bright processed surface.

[0003] However, in the prior art, existing mechanical parts such as metal gears will have burrs on their surfaces after production. In order to improve the appearance of the parts themselves, the surfaces generally need to be ground and polished. However, existing grinders can generally only grind and polish metal gears one by one, and the polishing efficiency is low, which affects the overall work progress. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: the existing grinders can generally only grind and polish metal gears one by one, and the polishing efficiency is low, which affects the overall work progress.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mechanical parts grinding and polishing device comprises a workbench, an electric telescopic rod is fixed on the upper surface of the workbench, and a placing table is fixed at one end of the electric telescopic rod, a positioning column is fixed on the upper surface of the placing table, and a protective ring is fixed on the surface of the placing table near the positioning column, a vent is provided on the surface of the placing table near the inner circle of the protective ring, and a closed frame is fixed on the lower surface of the placing table, a connecting pipe is fixed through one side of the closing frame, and an air pump is fixed at one end of the connecting pipe, a fixing table is fixed on the lower surface of the placing table, and the fixing table is fixedly connected to the air pump, a mounting table is fixed on the upper surface of the workbench, and a motor is fixed on the top of the mounting table, a rotating shaft is fixed on the output end of the motor, and the rotating shaft is connected through the mounting table, and a grinding disc is fixed at one end of the rotating shaft.

[0006] As a preferred implementation manner, rubber rings are fixedly connected to the surfaces of the positioning column and the surrounding ring.

[0007] As a preferred implementation, metal gears are placed at the positioning column and the retaining ring, and the height of the positioning column and the retaining ring is smaller than the thickness of the metal gears.

[0008] As a preferred embodiment, a stabilizing slider is fixedly connected to one side of the grinding disc, and the stabilizing slider is slidably connected to the mounting platform.

[0009] As a preferred embodiment, a shielding box is fixedly connected to the lower surface of the mounting platform, and a through opening is opened on the lower surface of the shielding box.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model has a positioning column and a protective ring to position and prevent the metal gear from moving when it is placed. The metal gear above the vent hole is adsorbed and fixed with the help of an air pump and a connecting pipe to prevent it from rotating during grinding and affecting the grinding effect. There are several fixed points for the metal gear on the placement table. With the help of an electric telescopic rod, several metal gears are moved to the grinding disc for unified grinding, which solves the problem that some grinders can only grind metal gears one by one, and effectively improves work efficiency.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-4As shown, the utility model provides a technical solution: a mechanical parts grinding and polishing device, including a workbench 1, an electric telescopic rod 2 is fixed on the upper surface of the workbench 1, and a placing table 3 is fixed at one end of the electric telescopic rod 2, the electric telescopic rod 2 plays the effect of lifting and moving the placing table 3, so that the metal gear placed on the placing table 3 is conveniently sent to the grinding disc 12 for processing, a positioning column 4 is fixed on the upper surface of the placing table 3, and a surrounding ring 5 is fixed on the surface of the placing table 3 near the positioning column 4, the positioning column 4 and the surrounding ring 5 play the role of positioning and blocking the metal gear when it is placed, a vent hole 6 is opened on the surface of the placing table 3 near the inner circle of the surrounding ring 5, and the vent hole 6 is close to one side of the metal gear, so that the metal gear can be adsorbed and fixed later, and a closed Frame 7, the setting of the closed frame 7 facilitates the air pump 9 to perform air extraction operations on multiple vents 6 in a relatively concentrated manner. A connecting pipe 8 is fixed through one side of the closed frame 7, and an air pump 9 is fixed at one end of the connecting pipe 8. With the help of the air pump 9 and the connecting pipe 8, the metal gears above the vents 6 are adsorbed and fixed to prevent them from rotating during grinding and affecting the grinding effect. A fixed table is fixed on the lower surface of the placement table 3, and the fixed table is fixedly connected to the air pump 9. A mounting table 10 is fixed on the upper surface of the workbench 1, and a motor 11 is fixed on the top of the mounting table 10. A rotating shaft is fixed at the output end of the motor 11, and the rotating shaft is connected through the mounting table 10. A grinding disc 12 is fixed at one end of the rotating shaft, and with the help of the motor 11 and the grinding disc 12, the metal gears can be polished.

[0021] Example 2

[0022] like Figure 1-4 As shown, rubber rings are fixedly connected on the surfaces of the positioning column 4 and the retaining ring 5. The surface of the rubber ring is relatively rough. When it contacts the metal gear, there will be a large friction force to prevent the metal gear from rotating, thereby improving the stability of the metal gear when placed. Metal gears are placed at the positioning column 4 and the retaining ring 5, and the height of the positioning column 4 and the retaining ring 5 is smaller than the thickness of the metal gear, which makes it convenient for the grinding disc 12 to grind one side of the metal gear well. A stabilizing slider 13 is fixedly connected to one side of the grinding disc 12, and the stabilizing slider 13 is slidably connected to the mounting table 10. With the help of the stabilizing slider 13, the grinding disc 12 can be more stably rotated and ground. A shielding box 14 is fixedly connected to the lower surface of the mounting table 10, and a through hole is opened on the lower surface of the shielding box 14. The shielding box 14 is used to block metal dust splashed during grinding to reduce the situation where the staff inhales metal dust and affects their health.

[0023] Working principle:

[0024] like Figure 1-4As shown, when the utility model is in use, the user first places the metal gears to be polished in order between the positioning column 4 and the retaining ring 5, then controls the air pump 9 to start, and performs suction operation on the vent 6 with the help of the closing frame 7 and the connecting pipe 8, so that the placed metal gears are adsorbed and fixed, then controls the electric telescopic rod 2 to extend and drive the placement table 3 to move upward, and finally allows the metal parts to contact the polishing disc 12, and the placement table 3 will also block the passage of the shielding box 14 after moving, and then turns on the motor 11 to drive the polishing disc 12 to rotate to polish multiple metal gears at the same time, effectively improving the polishing work efficiency. During this period, the shielding box 14 will prevent the metal dust generated by polishing from splashing and spreading to the outside, and at the same time, the setting of the stable slider 13 also makes the rotation of the polishing disc 12 more stable.
